Development of Ball Mobile Television Business Development Status Authors: People's Postal Telegraph
Since 2003, with the popularity of mobile data business, the improvement of mobile phone performance, and the rapid development of digital television technology and network , Major operators in the United States, Japan and other countries have launched mobile television business, which has attracted widespread attention. In my country, since March this year, China Mobile and China Unicom have also launched mobile TV business one after another, and mobile TV business is getting closer and closer to people. Today, mobile operators not only regard mobile TV business as a new growth point for mobile data business, but also regard them as the main business of 3G networks. (Thorough survey)
The development status of mobile TV business in various countries
The so -called "mobile TV business" is the use of operating systems and video functions to watch TV services. Obviously, due to the high penetration rate of mobile phone users and the convenience of mobile phones, mobile TV business shows a wider influence than ordinary TV. From the perspective of global situations, major mobile operators in various countries are actively committed to developing mobile TV business. Some of them have launched such businesses, while others plan to launch such businesses.
★ South Korea
The mobile phone TV business that South Korea is promoting is a digital multimedia broadcast business (DMB) that uses satellites and mobile networks to send video and audio programs. If the business is implemented, users can enjoy a variety of digital multimedia broadcast services provided by satellites through mobile terminals or vehicle terminals.
The main promoter of the Korean DMB business is SK. The reason why SK actively promotes the DMB business is mainly due to changes in the mobile communication market environment in Korea. As the South Korean mobile communications market is approaching saturation and market competition is increasing, SK urgently needs to find new sources of business income. DMB business is regarded as the core business that needs to be pushed in the next step. To this end, SK has established a new joint venture TU media company and led the "Mobile Development Agreement" participated by 19 mobile phone manufacturers.
In order to build a DMB business system, SK Telecom launched a special satellite in March 2004. The satellite is jointly owned by SK and Japan's mobile broadcasting companies, worth $ 310 million, and lift off in Florida, the United States. SK invested 94.5 billion won, accounting for 34.66 %, and the remaining funds were provided by Japan's mobile broadcasting companies. The satellite runs on the earth synchronization track of 35,785 kilometers over the equator. The main function is to launch TV programs to mobile phone, handheld communication equipment or vehicle devices.
SK is planned to start the commercial operation of DMB mobile broadcasting business this year to provide users with personalized TV shows. A spokesman for TU Media Company said the company will first launch 11 videos and 25 audio channels across the country. According to SK, the quality of the video image is equivalent to DVD, and the sound quality effect can reach the level of CD.
In to watch DMB mobile broadcast programs, users must buy new mobile phones that can accept satellite signals. At present, such mobile phones are about 700,000 won (5,000 yuan). In addition, the monthly use fee is about 32,000 won to 34,000 won (about 250 yuan). TU Media Company predicts that by 2006, it can have 2.2 million users, and by 2008, it hopes that the number of users can reach 6 million. According to a recent study in South Korea, in the next 10 years, the DMB business will effectively drive the development of related industries.
★ The United States
The mobile phone television business in the United States is achieved by mobile communication networks and streaming media. In November 2003, Idetic's Idetic company launched the MOBITV system. Through this system, users can use mobile phones to watch TV programs including ABC News, CNBC, Explore Channel and MSNBC. Although the Mobitv system achieves the goal of watching TV through mobile phones, the effect is very unsatisfactory. The conventional TV can display 30 frames per second. Human eyes and brains do not feel the pause of them, but Mobitv can only display 1 to 2 frames per second, so the picture is not coherent enough. At present, this system has been applied on the network of operator Sprint, and registered users can watch mobile TV programs including three music channels.
The April this year, American companies used Microsoft image compression technology -Windows Media 9 to develop a system that sent TV images to mobile phones in real time. The company installs Windows Media 9 decoding software on mobile phones using Microsoft Windows MOBILE operating system to achieve TV shows through mobile phones. It is said that the speed requirements of communication lines during transmission are only 8-12kbit/s, and the frame rate is 12-15 frames/s, which greatly improves the coherent of the screen.
It some companies are also considering the use of digital radio and television technology in the United States to provide mobile TV services, the most important of which are British radio and television operators -Guancheng International Company. The US microwave digital broadcast uses ATSC specifications, and ATSC cannot be accepted. To solve this problem, the US FCC opened a 5MHz band of 1670MHz to 1675MHz to provide multimedia services for mobile terminals. Guancheng International has obtained the authorization of the frequency band, so it has taken the initiative to provide such mobile TV business. At present, Guancheng International has built a DVB-H test facility in Pittsburgh, Pennsylvania, USA, and may build a radio and television network in the United States in 2005.
The Japanese radio and telecommunications companies jointly announced that they will launch digital radio and telecommunications programs specifically for mobile phones after April 2005. In view of this, Japanese mobile operators and all parties have developed mobile terminals that can watch digital TV programs. NTT DoComo and KDDI, the giants in the two Japanese mobile communications markets, have launched their own TV mobile phone product programs since 2003.
The May 2003 KDDI and the Japan Broadcasting Association (NHK) have developed a digital TV phone, but this phone is not equipped with a tunner for receiving digital radio and television signals, but uses a card -type wireless wireless wireless LAN module virtual receiving digital signal, the appearance of the handheld terminal is similar to PDA. In May of this year, KDDI and NHK used the "W11H" of the mobile phone "W11H" as the prototype. In addition to installing the BML browser and the video playback function, it also integrated a small module of the radio and television signal receiver and the OFDM demodulation circuit. This phone not only accepts ground digital TV signals, but also selects TV programs through online clicking.
NTT DoComo believes that users do not use their mobile terminals to watch TV programs for a long time, but more willing to watch their favorite programs at a specific time. In order to meet the needs of users, NTT DoComo launched the ONQ mobile terminal and proposed the concept of "metadata", and claimed that only such a mobile terminal was the terminal that really merged digital TV and mobile communication. It is understood that ONQ can search for interested scenarios by downloading and describing data (metadata) and other methods of program scenes, and switch between various scenarios at will. In addition, NTT DoComo also cooperated with satellite television company -Sky Perfect to combine the performance of digital TV phones.
The digital mobile phone TV business in Europe is still in the trial stage. But it is certain that Europe will adopt DVB-H digital mobile phone TV standards. At present, the largest trial projects are the Instinct Project of Pan -Europe, and the FINPILOT program carried out by French TDF Group in Finland, while another project, the mobile broadcast integration (BMCO) program is also carried out in Berlin. It is quite noticeable that the "" of the "" in Singapore's "" in Singapore demonstrated the DVB-H standard equipment. This is the first DVB-H device demonstration in Nokia in the Pacific.
In fact, some European operators also launched the business to watch TV programs with mobile phones, but the real -time nature is worse. For example, Finland's companies adopt WAP technology to watch the video business by establishing a connection with ELISA.TV. Mobile media website. Video content includes karaoke, music video, comedy fragments, talk shows and cartoon programs. In 2003, Polska Telefonia Cyfrowa (PTC) launched the "Video Era Omnix" business in Poland. Users can watch popular movies and TV programs through mobile phones.
has launched mobile TV services based on honeycomb mobile networks since this year.
In the end of March this year, Guangzhou Mobile provided the "mobile TV" business to global GPRS users. In May, the fashion business of the mobile data business brand "Silver Line" was officially launched. In terms of publicity and promotion, Guangzhou Mobile positions the business as "the first enjoyment of future life" through the method of free information fee trial and "mobile salon" activity. At the same time, Guangzhou Mobile also concentratedly purchased thousands of "TV phones" from manufacturers such as Siemens and Sony Ericsson to vigorously expand the market. In order to enrich the channel of mobile TV business, Guangzhou Mobile also cooperates with SP to integrate the content resources of mobile TV stations, jointly special SPs to develop software development and the organization and optimization of video resources, and the income is divided into the establishment proportion of the mobile dream network. Essence
Similarly, China Unicom also sets "mobile TV" as one of the focus of this year's value -added business, and launched its new business brand "video new trunk line". Unicom's mobile TV business relies on the CDMA 1X network. Users use mobile phones supporting streaming media to download a streaming media playback software through mobile phones, and set up a buffer to watch TV online. The current support mobile phones include three models such as Samsung 519pda.
In March this year, Guangdong Unicom launched the "mobile TV" event live broadcast while sponsoring the Athens Olympic Games Boxing qualifiers. This is the first public commercial test conducted by domestic operators. Guangdong Unicom will designate March as a free experience month for the "mobile TV" service, free traffic fees, and open free experience areas in the main business halls.
The problems facing the development of mobile TV business
★ Control problems
The biggest problem currently facing mobile TV business is mainly the problem of control. This is because countries generally have different policies in the field of broadcasting and communications, and are managed by different government departments, and have strict restrictions on companies in the corresponding fields. Taking South Korea as an example, South Korea's radio law prohibits SK communication companies from using its mobile broadcast network to provide ground TV programs. SK has already submitted an application for DMB business, but has not been approved. Although SK said it will continue to apply, if the Korean government still adheres to such restrictions, the DMB plan of SK will be a serious blow.
The is the same in my country. At present, the policy of the State Administration of Radio, Film and Television has not yet been promulgated, and the specific operations cannot be rely on. If the State Administration of Radio, Film and Television does not approve the business of receiving TV programs through a mobile phone, consumers will not enjoy this service.
It, the mobile TV business will also involve other intellectual property issues such as copyright.
★ The maturity of technology
It mobile TV business also needs to solve a series of technical problems, such as network transmission rate, short battery life, and miniaturization of the terminal. At the same time, It is also necessary to formulate relevant technical standards and coordinate development with content service providers.
For operators using mobile networks to launch mobile TV services, the limit of network capacity and data channel rate is the biggest problem. At present, Chinese mobile operators mainly play mobile TV programs through 2.5G or 2.75G network transmission technology. Due to the limited network transmission bandwidth, if the number of users using mobile TV business increases, there will be problems with the network.
Is when using a mobile TV business, the consumption of the opponent battery is very large. The existing mobile phone battery is generally shorter, and it can only be used for about one hour if watching TV.
It, if the combination of digital radio and television and mobile communication provides mobile TV business, there should be no major problems in accepting signals, but it must face problems such as inconsistent technical standards.
★ Tariff problem
First of all, there are still very few types of mobile phones with watching TV functions, and the average price is above 5,000 yuan. The price of some products even exceeds 7,000 yuan Essence How many users can be accepted by such prices and can it be popularized?
Secondly, business use tariffs may be very expensive. Sprint's mobile TV services are charged $ 9.99 per month, and network access fees are also required. Some people estimate according to the traffic. China Unicom's mobile TV business reaches 25 yuan per minute. If you see an hour, it is 150 yuan. What kind of users can bear such a tariff level? What kind of charging method to operate in the future is indeed a difficult problem for users to accept and make money.
The development trend of mobile TV business
At present, although the development of mobile TV business still faces many difficulties, in the long run, with the increase of mobile communication network bandwidth, the increase in the bandwidth of mobile communication networks increases width. The level of business tariffs has declined, with the increasing popularity of video mobile phones, mobile TV business will develop rapidly and form a considerable market scale. A report from IMS Research shows that by 2010, 120 million users in the world will watch live TV programs, and Asia will become the most popular region of mobile TV services, followed by the United States, Europe, the Middle East and Africa.
In from the technical system adopted by the operator, users who watch TV programs on mobile phones through digital TV broadcasting may take advantage of the majority, and users who use mobile networks to watch TV programs mainly watch short viewing shorts Time programs, such as major news, ball games and entertainment wonderful movies.
